### **Pros and Cons of Buying a Mercedes-Benz W207 E350 (2012 2017) with Electric Power Steering Rack Pinion (Part No. A2074601800)**

#### **Pros**

1. **Reliability of the V6 Biturbo Engine**

The 3.5L V6 biturbo engine (M276) in the E350 is a well-regarded powerplant known for durability, especially when maintained properly. With proper oil changes and cooling system upkeep, it can easily exceed 200,000 miles without major issues.

2. **Comfortable and Refined Ride**

The W207 platform is known for its smooth suspension tuning, quiet cabin, and high-quality materials, making it a comfortable choice for daily driving, especially on highways.

3. **Strong Resale Value**

Mercedes-Benz retains strong resale value compared to many luxury competitors, meaning you ll recover more of your investment when selling or trading in.

4. **Advanced Safety Features**

- **ESP (Electronic Stability Program)**

- **Automatic Emergency Braking (AEB) in later models (2014 )**

- **Adaptive Cruise Control (DISTRONIC PLUS in some trims)**

- **Multiple airbags and pre-collision systems**

5. **Electric Power Steering (EPS) Advantages**

The EPS system (with the pinion rack in question) is more responsive than hydraulic steering, reduces effort in parking, and is generally more reliable than older hydraulic systems. It also eliminates power steering fluid leaks, a common issue in older Mercedes models.

6. **Available Luxury Features**

- **Heated/ventilated seats**

- **Ambient lighting**

- **Bluetooth connectivity (in later models)**

- **Comfortable ergonomics and driver-focused controls**

7. **Good Fuel Economy for a V6**

While not a hybrid, the E350 achieves around **18 22 MPG combined**, which is reasonable for a V6 luxury sedan, especially with modern fuel injection and turbocharging.

8. **Aftermarket Support**

The W207 has a strong aftermarket presence, with availability of parts, tuning options, and performance upgrades (e.g., exhaust, suspension, or engine tuning).

#### **Cons**

1. **Higher Maintenance Costs**

Mercedes-Benz vehicles, especially luxury models, come with premium pricing for parts, labor, and diagnostics. Routine maintenance (e.g., oil changes, timing belt replacement) can be expensive compared to mainstream brands.

2. **Potential Electrical Gremlins**

- **Faulty sensors (e.g., camshaft position sensor, MAF sensor)**

- **Infotainment glitches (especially in older MBUX-free models)**

- **Intermittent warning lights (e.g., oil pressure, ABS, or traction control)**

These issues can be frustrating and may require dealer visits.

3. **Transmission Reliability Concerns**

The **7G-Tronic automatic transmission** (6-speed) is generally robust but can develop **slipping, rough shifting, or delayed engagement** over time, particularly if fluid changes are neglected. Some owners report needing **transmission rebuilds** around 100,000 150,000 miles.

4. **Common Wear Items**

- **Timing belt & water pump** (must be replaced every **100,000 miles** or 7 years, whichever comes first).

- **Suspension bushings & struts** (wear out around **80,000 120,000 miles**).

- **Brake pads & rotors** (higher-end materials mean higher replacement costs).

- **Coolant system leaks** (especially from the **thermostat housing or water pump**).

5. **Electric Power Steering (EPS) Specific Issues**

- **Stiffness or resistance in steering** (often due to worn bushings or seized components).

- **Whining or grinding noises** (may indicate internal wear or contamination).

- **Electrical faults** (e.g., EPS control module issues, wiring harness problems).

Replacing the rack is **expensive** (typically **$1,500 $2,500** installed), and labor-intensive due to underbody access.

6. **Infotainment Limitations**

The **COMAND system** (pre-MBUX) can be **slow, glitchy, and difficult to navigate**, especially when updating software. Bluetooth and phone connectivity may require **third-party adapters** in older models.

7. **Depreciation & Insurance Costs**

While resale value is decent, luxury vehicles still depreciate significantly. Additionally, **insurance premiums** for a Mercedes are often higher than for comparable non-luxury sedans.

8. **Rust & Underbody Corrosion**

The W207 is prone to **underbody rust**, particularly in the **wheel wells, subframe, and exhaust mounts**, especially in snowy or salted regions. A thorough inspection of these areas is **critical** before purchase.

9. **Limited Off-Road Capability**

The E350 is a **front-wheel-drive (FWD) sedan**, meaning it lacks the traction and capability of an AWD or 4WD model. Poor weather or slippery roads may require more caution.

10. **Resale Market Saturation**

The W207 has been in production for over a decade, meaning there is **a large used market** with plenty of competition. This can make it harder to sell quickly or at a premium price.

### **Key Considerations Before Purchase**

1. **Service History**

- **Oil changes** (every **5,000 7,500 miles** for synthetic).

- **Timing belt & water pump** (must be done if over **100,000 miles**).

- **Transmission fluid** (should be changed every **60,000 100,000 miles**).

- **Coolant flush** (every **5 years or 60,000 miles**).

2. **Electrical & Sensor Checks**

- Scan for **check engine lights (OBD-II codes)**.

- Test **ESP, ABS, and traction control** functionality.

- Inspect **wiring harnesses** for fraying or corrosion.

3. **Steering System Inspection**

- Listen for **whining, grinding, or stiffness** in the EPS.

- Check for **leaks or damage** around the rack.

- Test **steering feel** should be smooth, not jerky or heavy.

4. **Suspension & Alignment**

- Look for **uneven tire wear** (indicates alignment or bushings).

- Check for **excessive play in steering** (could mean worn ball joints or tie rods).

5. **Underbody Rust Inspection**

- Lift the car and inspect **wheel wells, subframe, and exhaust mounts**.

- Check for **dents or corrosion** in the **splash shields**.

6. **Test Drive Focus Areas**

- **Acceleration & shifting** (should be smooth, no hesitation).

- **Braking performance** (listen for squeaking or grinding).

- **Steering response** (should be precise, not sluggish).

- **Noise levels** (excessive humming, rattles, or whining).

---

### **Final Recommendation**

You **prioritize comfort, luxury, and refinement** over raw performance.

You **have a budget for maintenance** and can afford potential repairs (especially transmission, suspension, and electrical issues).

The **vehicle has a full service history**, especially for **timing belt, transmission fluid, and coolant changes**.

You **inspect the EPS rack thoroughly** if it shows signs of wear (noise, stiffness, or leaks), consider whether the repair cost is justified.

You **plan to keep it for at least 5 7 years**, allowing you to recoup some of the initial investment.

The **transmission shows signs of slippage or rough shifting** (transmission rebuilds can cost **$3,000 $5,000**).

The **EPS rack is noisy, stiff, or leaking** replacement is **expensive and labor-intensive**.

The **underbody has significant rust** (structural integrity could be compromised).

The **seller cannot provide maintenance records** (especially for **timing belt, oil changes, and coolant flushes**).

You **cannot afford unexpected repairs** luxury vehicles require **more frequent and costly maintenance
